T0 all wham z't may concern:

Be it known that I, WILLIAM H. VON HAGEL, a citizen of the United States, residing at Baltimore city, and State of Maryland, have invented ngw aI1d-useful Improvements in 011 Burners, of which the following is 21 specification. l

This in vention consists 1n certa1n 1mprovements I hzwe made 150 oil brners f0r use in domestic furnaces of all kinds.

Oil burners of this type arewell known and there are many of them 011 the mark'et. They are either of the force feed type, comprising a blower; the natural draft type, or of the typ usizig a spray of steam m1xed with the oil.

My invention is a brner of the natural draft type and comprises, as usna1, an oil pan having central air openin and a 1'1 overflow otlet adapted to re'ce1ve th 011 throgh a central pipe, a skirt depending from und srrounding-the pan and by which the burner 'is supported; on'the grate, a soreader ont0 Which the oil is.fed and a cap sitting 011 said spreader, whereby an annu- 1211 flame is Produced.

In the practical use of such burners, I

'have noticed certain defects or objectiqnable features, to remove or obviatewh1ch is the purpose o'f the hereinafter described improvements constituting my invention.

Burners of this typehave heretofom, as f:u as I am aware, been merely placed upon the grate and scured in place b the fir'e c1ay packing, no means having een pro vided for leveling them or positively securing the'm in p1ace. Furt'hermore, the skiif; has merely surrounded theedge of the an, the clay packing being depended up0n 130 prevent air passingup around the skirt. I hzwe found, however, that air leaks very soon developed, the clay becoming loosened from the periphery Of the skirt. Furthermore, it has been customary to screw the spreader onto the end of the oil inl et pipe which projecis through the center of the pan. Therefore, when it became necessary t0 remove or rehew the spreader, the inlet pipe woulc1 fall down and it became necesmary to open up the front 015 ehe furnace before a new s'preader could be connected. All these disadvantages are obviate by the present improve c0nstruction. These improvements am illustratedi in the accompanym drawing, inwhich,

I*igure 1 is 22 central vertical section -with a spreader and oil inlet 1bhrough the burner online 1-1 )f FigQ 2,

and Figure 2 is a plan vieW, with a Portion of the cap broken away.

In these views, 1 represents the leveling ring; 2 the pan With central hub 3, sur- "rounded by air ope'nings 4; 5 the Skirt o1 draft cyl inder by Which the burner is supported 011 the grate 6; 7 'the oil spxeaderfi of usual construction, with a threaded stem 8, screwing into hub 3; 9 the oil inlet ipe threaded into the lower end ofsaid ub, and 10 the cap which sits on the spreader.

The ring 1 is leveled by means of the four screws 11 and is th'e'n c1amped down to the gxate by the two bolts 12, passed through a platte or stri 13, beneath the grate bars. The screws 11 ear on steel plates 14.

The pan 2 is flanged, as shown, to rest on ehe ring and. the skirt 5 fits between the Wall of the pan and the inside 0:E the ring. This construction prevents anyair leakage around the skirt.

The pan has the usal overflow openin 15, connecixad by a pipe, not shown, wit a cheok-valve bucket to .shut oif the oil if the flame is .extinguished. VVhen it becomes necessary 110 renew the spreader, 'it can be unscrewed from the hub 3 without disturbin the oil inlet pipe 9. The ibration, in-

ci ent to the operation of the burner, cannot cause it to become loose or shift its position and, corisequently, thgare is no dang}1:r ofair leaks developi'ng. If at any time t e an needs leveling, the screws 11 are. avai able for eas 'manipulation. Having thus escribed my i nventionwhat I claim 1s:

1. In an oil burner, the combination with a flanged pan having a hub Iotengagement ipe, of a ring engaging under the flange 0 said pan, an annular sheet metal sk1rt, the upper edge of which fits between said ring und pan under the flange of the la'bter, und. ;b0lts adjustably supporting said 'ring fnom the grate.

2. An oil Immer, comprising a cylindrical skirt adapbed to rest on. the gra'te of a' furnace, a flanged pan resting on the npper edge of said skirt, a ring surroundlng said upper edge and engaging the underside of said. flange, screws threacled through saic1 flange and abutting the grM-q mnd-bolts to 1 clamp said ring to said gxate.

3. An oil .rner for domestic furnacew comprising a cylinder adapted 130 saut 011 of s'aid pan to claimp it and said cylinder the grate, a flanged pan adapted to be sup- -to the grate, und leveling screws for said ported on the to'p ed%e of s:aid c'ylingier, pan abutting said grate.

an oil spreader central y suplwrtedin said In testimony whereo f I have hereunto set 5 pan, the latter havin airpassa es leadin my band.
